What two numbers have a GCF of 755?

Here we will explain and show you how to find what two numbers have the Greatest Common Factor (GCF) of 755.

There is actually an infinite number of answers to this question. First, note that both the numbers we are looking for must be multiples of 755. Below is the beginning list of multiples of 755 (1 through 7) in numerical order.

1. 755
2. 1510
3. 2265
4. 3020
5. 3775
6. 4530
7. 5285
etc...

Two numbers that have a GCF of 755 can be 755 and any other number on the list above. Thus, two numbers that have a GCF of 755 are:

755 & 1510
755 & 2265
755 & 3020
etc...

That is not all! Any combination of any multiple of 755 and "odd" multiples of 755 will also have GCF of 755. We numbered the multiples above so it would be easy to identify the "odd" multiples (number 1, 3, 5, 7, etc). Thus, here are some more examples of two numbers that also have a GCF of 755.

1510 & 2265
1510 & 3775
3020 & 3775
3020 & 5285
etc...

Like we stated above, there are infinite combinations of two numbers whose GCF is 755. The lists we created can go on forever.
